2019 - 2023 SQ7 4.0t Quattro Stage 1

What’s This Tune All About?

Slide into the cockpit, hit that start button, and hear the 4.0T V8 growl to life — this ain’t your dad’s SUV anymore. With our Stage 1 ECU tune, the SQ7 becomes an absolute menace in a luxury disguise. Torque hits like a freight train, throttle response is razor sharp, and that twin-turbo pulls like it’s chasing something.

Every freeway on-ramp becomes your launch pad. Every stoplight? A challenge accepted. Whether you’re hauling the family, showing off to the boys, or gapping unsuspecting “built” cars in a 3-row sleeper — this tune makes the SQ7 punch way above its weight class.

It’s refined when you want it. Ruthless when you don’t.

4.0L TFSI V8 — From Civilized to Savage

From the factory, the 2020 SQ7’s twin-turbo V8 is no slouch — but we take it from strong to seriously unhinged. With BDT’s Stage 1 ECU tune, you're looking at up to 560 HP and 675 lb-ft — and all that torque hits early and hard.

What’s that mean on the street? Instant roll-ons. Faster 60–130s. And that satisfying moment when the “faster” car in the next lane gets walked by a 3-row Audi.

It’s the sleeper SUV you didn’t know you needed — until now.

Crackle Pops — Because V8s Should Sound Angry

Lift off the throttle and let it talk back. BDT’s crackle tuning adds controlled overrun drama that turns heads and drops jaws — even on a factory exhaust.

Choose your level of spice:

• Low – Subtle, tasteful, perfect for daily drivers

• Medium – Playful and loud enough to get noticed

• High/Intense – Absolutely unhinged. Pops, bangs, even flames (with proper setup)

Whether you’re rolling through a tunnel or letting off at a meet, it’s audio violence in the best way possible. This isn’t just noise — it’s part of the experience.
